443 + This variable designates a global photon map to be generated by
444 + .I mkpmap(1)
445 + and used to accelerate rendering.
446 + The file name must be followed by the number of photons to be stored
447 + in the map, and this number may be followed by a bandwidth for rendering.
448 + There is no default value, meaning that a global photon map will not

452 + This variable designates a caustic photon map to be generated by
